Am I pregnant?

Hey guys. So I just had my period on the 5th, 6th, and 7th. But last night I was in the shower and the smell of the conditioner I have used since I was young made me nauseous. Then today my boyfriend got chicken wings for dinner, and if you know me, you know I LOVE CHICKEN WINGS, but they also made me nauseous when he brought them into the car. I have had this migraine that I can’t get rid of and I have been really moody lately? Am I pregnant or just odd? And if I’m not pregnant does that mean something? I’m trying not to get my hopes up again. We’ve been having unprotected sex for almost a year now and still nothing.
